Abstract
The new Kibble balance at the National Institute of Standards and Technology (NIST) is part of the Quantum Electro-Mechanical Metrology Suite (QEMMS). Two quantum standards are incorporated directly in the electrical circuit of the Kibble balance for the realization of the unit of mass. This eliminates the need for external calibration in the Kibble balance experiment. The targeted uncertainty is 2 μg on a 100 g mass and a range from 10 g to 200 g will be covered. We introduce the measurement concept of the QEMMS, show the current state of development and publish first measurements proving the performance of the newly designed balance mechanics.
